errno_t _cgets_s( char *buffer, size_t numberOfElements, size_t *pSizeRead ); errno_t _cgetws_s( wchar_t *buffer size_t numberOfElements, size_t *pSizeRead ); template <size_t size> errno_t _cgets_s( char (&buffer)[size], size_t *pSizeRead ); // C++ only template <size_t size> errno_t _cgetws_s( wchar_t (&buffer)[size], size_t *pSizeRead ); // C++ only
_cgets_s and _cgetws_s read a string from the console and copy the string (with a null terminator) into buffer. _cgetws_s is the wide character version of the function; other than the character size, the behavior of these two functions is identical. The maximum size of the string to be read is passed in as the numberOfElements parameter. This size should include an extra character for the terminating null. The actual number of characters read is placed in pSizeRead.
If an error occurs during the operation or in validating the parameters, the invalid parameter handler is invoked, as described in Parameter Validation . If execution is allowed to continue, errno is set to EINVAL and EINVAL is returned.
In C++, using these functions is simplified by template overloads; the overloads can infer buffer length automatically (eliminating the need to specify a size argument) and they can automatically replace older, non-secure functions with their newer, secure counterparts. For more information, see Secure Template Overloads.
